Which on the of these should I get for keeping me warm during the colder mornings. Don't cycle if there's black frost warning on the morning news so it will not be really, really cold, really anything just above freezing. At min I wear two base layers (helly hansen and some other) then a fleece lined cycling jumper type thing (Gill). Keeps me warm but the base layer stinks as I sweat like a pig (I do that anyway regardless of how much or little I wear) so I have been told that the merino wool base layers don't stink so I will get this as a Christmas Pressie. Anyways not sure which would be more appropriate. This one: http://www.howies.co.uk/product.php/404/16/ or this one: http://www.howies.co.uk/product.php/794/16/ Not sure if the first would be too heavy or conversely would the second be too light in colder weather. My own instincts are telling me to get the first however not having much experience of cycling in the cold and definitely having never worn merino wool before not really sure. Any advice appreciated.
